Definitions

  • the present invention relates generally to the field of insulating flammable materials against high temperatures and flame in order to prevent those materials from igniting and releasing smoke, and more particularly, to an insulating arrangement for a vehicle seat include a plurality of flame-resistant layers arranged to provide a flexible encapsulating cover for flammable seat materials.
  • Vehicle seats such as aircraft seats, typically include a frame defining seat back and bottom portions for supporting the seat occupant.
  • at least the back and bottom portions are typically covered with some type of resilient cushioning material, such as foam and like materials.
  • the cushioning material is typically covered with a robust fabric that moves with and contours to the shape of the foam. The fabric covering may also function to maintain the cushioning material in place and may be patterned or colored to provide decoration to the seat.
  • the fabric covering For safety and fire prevention, it is not uncommon for the fabric covering to be made from or treated with a flame-retardant material in order to decrease the flammability of the covering and the cushioning material beneath it.
  • conventionally treated fabrics are not able to adequately insulate the underlying cushioning materials from radiant heat flux resulting from a fire within the passenger compartment.
  • cushioning materials exposed to sufficient heat flux can cause the materials to ignite and/or release smoke and fumes.
  • the contribution of heat, flame and smoke density to the cabin atmosphere from additional burning materials increases the rate at which the fire spreads and decreases the time in which passengers have to escape.
  • Federal Air regulation 25.853(d) details testing requirements for determining the acceptability of materials utilized in aircraft interiors.
  • Regulation 25.853(d) includes two separate tests: (1) the OSU Rate of Heat Release Test, and; (2) the Smoke Density Test.
  • the OSU Rate of Heat Release Test involves exposing aircraft interior cabin materials to incident radiation heat flux, and measuring the rate at which a burning item releases heat. The OSU test can be used to determine at what temperature certain interior materials will ignite, thus starting a fire or contributing to the spreading of an existing fire.
  • the second test, the Smoke Density Test is used to measure and observe the relative amounts or density of smoke produced when a material is burned. This test is also useful in determining the smoke contribution of a burning material to the aircraft cabin atmosphere and the decrease in visibility that occupants will encounter in exiting the passenger compartment during a fire.
  • insulating layer between a flammable material and high temperatures in a passenger compartment, thus protecting the material and decreasing its hazard potential.
  • a layered insulating cover for flammable cushioning materials to shield the materials from heat flux that could cause the materials to ignite and/or contribute smoke to the cabin environment.
  • a desirable insulating cover would be flexible so as not to reduce the comfort of the cushioning material, and would obviate the need to treat or construct the cushioning material using flame-retardant additives or materials.
  • an insulating cover is provided for decreasing the hazard potential of underlying materials.
  • an insulating cover is provided for substantially surrounding or encapsulating flammable material.
  • an insulating cover is provided for positioning between a fabric seat cover and a flammable cushioning material to insulate the material from heat flux that could cause the material to ignite and/or give off smoke.
  • an insulating cover for flammable material is provided that is sufficiently flexible such that it conforms to and moves with the underlying flammable material as well as a covering fabric.
  • an insulating cover for a seat cushion is provided that minimally reduces the comfort provided by the cushion.
  • an insulating cover for an aircraft passenger seat cushion, a padded partition or another padded structure including a plurality of various types of fire blocking material arranged upon one another.
  • an insulating cover for flammable materials is provided.
  • the insulating cover is positioned between the flammable material and the heated environment, and partially or substantially surrounds or encapsulates the flammable material.
  • the insulating cover functions as a barrier bet wen the flammable material and heat and flame.
  • the insulating cover is arranged over the flammable material and benaeth a protective, decorative fabric cover.
  • the insulating cover may be positioned between a protective fabric and a seat cushion, between a protective fabric and a partition pad, or arranged on any other flammable material.
  • the insulating cover is preferably flexible so as to conform to, move with and not detract from the comfort of the seat or padded surface.
  • the insulating cover includes a plurlaity of layers arranged symmetrically about an aluminum film or ceramic fabric material layer, In alternative embodiments, the layered arrangement may be non- symmetric about the aluminum film or ceramic fabric. In additional embodiments, the layered insulating arrangement includes stacking multiple layers of aluminum film or ceramic material, adhesive and fire-blocking material. In another embodiment, the insulating assembly includes a predetermined number of stacked layers of aluminum film or ceramic fabric and fire- blocking material secured together with an adhesive.
  • multiple layers of aluminum film, ceramic fabric, and fire-blocking material may be stacked directly upon each other to achieve a desired level of insulation.
  • the embodiments herein provide varying layered arrangements of insulting materials and fire- blocking materials that can be arranged in a number of ways to insulate materials from high temperatures and flame.
  • the present invention provides a passenger seat including a seat frame defining or supporting seat back and bottom portions.
  • a cushioning material such as a resilinet foam or like cushioning material.
  • the cushioning materials are cover with an insulating cover including a predetermined layered arrangement of nonflammable and fire-blocking materials that may optionally be secured together with adhesive.
  • the layered insulating cover is flexible so as to conform to, move with and cover at least a portion of the underlying cushion.
  • the seat further includes a robust, decorative fabric cover arranged on and covering the insulating cover.
  • the fabric cover is preferably also constructued from non-flammable material.
  • the top layer of the insluting cover adjacent the seat occupant is a decorative fabric to obviate the need for a spearately applied and independent fabric covering.
  • the insulating covers includes layers of aluminum film or ceramic fabric and fire-blocking material.
  • FIG. 1 is a cutaway perspective view of an aircraft passenger seat illustrating a layered insulating cover for flammable seat material in accordance with an embodiment of the present invention.

While the insulating cover has been described with reference to aircraft and passenger compartment components, it is envisioned that the insulating cover or components thereof may be used to insulate other flammable materials found elsewhere, such as other vehicles and floor coverings, wall coverings, insulation, cargo compartment liners, air ducts, trim strips as well as molded parts. Various details of the invention may be changed without departing from the scope of the invention. Furthermore, the foregoing description of the preferred embodiments of the invention and best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation.
